A straight transfer pipe of length L = 10 m and D = 1 cm carries a liquid in highly turbulent flow at a pressure drop DPinit; this pipe must be altered to accommodate a new unit operation in a process, but must maintain the same flow. The old and new geometry are indicated in the sketch below. This adds length DL = 1 m, and adds 2 short-radius 90-degree bends; the diameter remains the same. What fractional increase in pressure drop from DPinit is required to maintain the same flow rate?
